Error using Dictionary password on solaris 11.4

I have the following error when trying to use a key dictionary on a Solaris 11.4 server:

password dictionary missing.

Unexpected failure. Password file/table unchanged.

This is the file configuration /etc/default/passwd

MAXWEEKS=8

MINWEEKS=1

PASSLENGTH=8

NAMECHECK=YES

# HISTORY sets the number of prior password changes to keep and

# check for a user when changing passwords. Setting the HISTORY

# value to zero (0), or removing/commenting out the flag will

# cause all users' prior password history to be discarded at the

# next password change by any user. No password history will

# be checked if the flag is not present or has zero value.
